Suspension System 의 가속내구해석

In the development stage of vehicle structures and components, there is a tendency to increase using numerical simulation methods for the estimation of fatigue strength. The advantage numerical simulation methods are especially marked when it is applied at a very early stage in the development process. The essential profit is the reduction of test loops with different structure and component variants due to pre-optimized prototypes by numerical simulation. However, the estimation of fatigue strength has been difficult since fully integrated computer aided engineering(CAE) technique for durability evaluation was not developed. In this study, simple and accurate analysis technique is suggested for farigue strength evaluation through virtual proving ground(VPG) technique. And also, we verify the presented analysis method through durability evaluation of the knuckle of passenger car.
